Summary

Aspects of the ovicidal activity of the fungus Verticillium chlamydosporium Goddard on the eggs of Ascaris lumbricoides were observed in the laboratory using a scanning electron microscope. The hyphae of the fungus form structures which are considered to be penetration organs. The hyphae also form a network over the surface of the eggs. After penetration of the eggs, the hypha or hyphae ramify and the embryos are destroyed.
